Why "Ballpark" Coverage Amounts Are a Costly Mistake

Many people are told to buy "10x income" or "15x income." While these rules of thumb are simple, they often miss critical details:

• Outstanding debts
• Mortgage balance
• Number of dependents
• Childcare or college costs
• Length of income replacement needed

Your coverage amount should be customized, not guessed.

The 5-Step Formula to Calculate the Exact Term Life Insurance Amount You Need

This proven method ensures every dollar is accounted for.

Step 1: Add Up All Immediate Financial Obligations

These are the expenses your family would face right away if you were gone tomorrow.

Include:

• Mortgage payoff balance
• Car loans
• Credit cards
• Personal loans
• Medical bills
• Funeral and burial costs

Typical funeral expenses alone range from $10,000–$15,000.

Step 2: Calculate Income Replacement (The Most Important Step)

This is where most people underestimate coverage.

Ask yourself:

• How many years would your family need your income?
• Until children are grown?
• Until retirement age?

Formula:

Annual income × years needed = income replacement amount

Example:

• Annual income: $75,000
• Years needed: 20
• Income replacement needed: $1,500,000

This ensures your family can:

• Pay monthly bills
• Maintain their lifestyle
• Avoid draining savings

Step 3: Factor in Education Costs for Children

College is one of the most overlooked costs.

Average estimates:

• In-state public college: $100,000+ per child
• Private college: $200,000+ per child
• Multiply by the number of children you want to support.

Step 4: Subtract Existing Assets and Savings

Now reduce the total by resources already available.

Subtract:

• Savings accounts
• Investments
• Existing life insurance coverage
• Employer-provided life insurance (if portable)

⚠️ Be conservative—employer coverage often disappears when employment ends.

Step 5: Choose the Right Term Length (Just as Important as the Amount)

Coverage amount and term length work together.

Common term lengths:

• 10 years – Short-term needs, bridge coverage
• 20 years – Most popular for families
• 30 years – Maximum long-term protection

Choose a term that lasts until your largest obligations are gone (mortgage paid, kids independent).
